what causes a 2004 kia opimalx to die after apox. 10 miles.?

Has G15 ground under drivers seat been checked? vehicle ever had water damage?

i have checked all wiring under the drivers seat. I was unable to find a ground. Is it bolted to the chassis? The car has never had water damage. It has been hit on the passanger side front and was rebuilt prior to us buying it.Any further info or ideas would be appreciated

When it stops pull plug wire check for spark

when it stops i still have spark and i can hear the fuel pump running when i try to start it. If it does manage to start it dies immediately.... Could it possibly b a bad gas cap? the check engine light came back on with misfire on cyl. 2&3 cam sensor and tps.....i noticed when i was driving and i set the cruise the engine would rev and cruise would stop working. Could this possibly have anything to do with my current problem? any further help would be greatly appreciated

What are codes in P0xxx format

i dnt know the code numbers. the previous post told the description of the codes. no matter what we do we have the same results although all those parts have been replaced. I dnt understand why we can drive it up to 15 miles before check engine light comes on and it dies and wont restart for aprox 30 min

Codes will help me diagnose also has fuel pressure been checked?

no the fuel pressure hasnt been checked. What would cause it to have adequate fuel pressure for 15 miles then stop then wait 30 min and have fuel pressure again? I will contact the mechanic that checked it and get the codes. One of them was a 340.He is bringing me the printout of the aditional codes, i will send them as soon as i get them

Well fuel pumps do fail when overheated due to worn bearings and stop let cool will run for awhile then stop

i just replaced the fuel pump along with the other parts i listed. the codes that it keeps giving after replacing all these parts and clearing the codes are: p0340,p0303,p0302,p0300

Has wiring to MAF and CMP been checked? have tried wiggling CMP connector and MAF see if that causes stalling. When it dies try spraying carb cleaner into intake see if it lights.need to determine what fails

all wiring and connections have been checked. last night while working on it, before it died the check engine light came on for bout a sec then turned back off for a few min. it did this several times then died.

MAF will cause stalling as well as CMP and 340 is comming up. Have done some checking KIA timming belts can brek one tooth still run good but CMP is off so sets codes 340 and 300,301,302,303,304. pull top cover off belt roll engine over see it damage to belt

i check the timing belt. all the teeth are intact and there doesn't seem to be any wear or cracks.

Any other ideas on how to fix it?

disconnect MAF see what happens

My Optima does the same is better to check with the kia dealer I went to 3 diffrent auto mechanic none of them new what was wrong with it, they checked it for $45, also did you check for any recalls?

I have checked it with MAF unhooked. It still does the same thing. I am going to check about any recalls.Are there any other ideas or solutions to this problem? Any help would be greatly appreciated

I just checked and there are no recalls for a 2004 kia optima for this type of problem. We bought this car used and it started this 2 1/2 weeks after we got it. Being it was used it was as is. We have had it 9 months and still cant drive it after spending a butt load in parts and mechanic bills.....Any help would be appreciated

I am having the exact same problem only some times mine will go a hundred miles before it starts to act up i took it to a kia dealer and they first said it was the computer which they replaced then they said the crankshaft sencer which they replaced i took it to another mechanic who kept it for a month said he checked all the wiring and it wouldnt act up. it will idle all day and not have a problem i have replaced everything i can think of please somebody help

ok folks. I finally got it fixed. It turned out to be the small timing belt going to the balance shaft. It had a slight amount of slack in it. Once i tightened the tensioner pully for that belt , and I also sanded the disk that the crank position sensor reads, the car has gone a 1000 miles without any problems. I hope this helps anyone else that has had this problem. Thanks for everyones help
